Filed: 1992-12-14
Abstract: PURPOSE:To provide the styrene copolymer which has a good moldability and is thermally decomposable at a low temp. by copolymerizing styrene with alpha- methylstyrene in a specified wt. ratio making the resulting copolymer have a specified thermal decomposability. CONSTITUTION:The copolymer comprises 30-90wt.% styrene monomer units and 70-10wt.% alpha-methylstyrene units and has a thermal decomposability (expressed by a wt. loss by thermal treatment) of 99% or higher under heating at 385 deg.C under a reduced pressure for 30min. Since the mol.wt., mol.wt. distribution, and microstructure of the copolymer can be changed with the changes in polymn. conditions such as the type of an initiator used, constitution of the monomer mixture, polymn. temp., etc., the copolymer having desired properties is obtd. by controlling the polymn. conditions. When the mol.wt. of the copolymer is too low, the decomposability becomes bad, and too high mol.wt. makes its moldability poor. The pref. mol.wt. is 1,000-1,000,000.

IPC: G02B5/28
Filed: 1991-12-17
Abstract: PURPOSE:To obtain the high-quality light absorptive film which lessens the generation of stresses and does not crack by forming the film of the specific layer of the light absorptive film by using SiO2.

The difference between a phase of a ray A emitted from the film and a phase of a ray B passing a binder is required to be set at 1/4lambda in the case of use for a phase film having 1/4lambda phase difference and, therefore, the MgF2 is not completely formed of the SiO2 but if the number M of the films to be laminated is an even number, the film of the (M/2)+ or -n [where n=0, 1, 2,...,{(M/2)-2}]th layer is formed of the {SiO2 and if the number M is an odd number the film of the {(M+1)/2)+ or -n} [where n=0, 1, 2,...{[M+1)/2],-2)}]th layer is formed of the SiO2. The stresses generated by the MgF2 in the first half of the films are offset by the central part of the films and the light absorptive film which is suppressed in the film thickness over the entire part and is easily workable is obtd.

Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To realize a superior operating efficiency without increasing a size of a heat exchanger or increasing an enclosing amount of refrigerant even in the case that refrigerant having its critical temperature not higher than 90 deg.C is used. SOLUTION: An air conditioner is provided with a refrigeration cycle in which a compressor 1, a four-way valve 2, an outdoor heat exchanger 3, an expansion valve 4 and an indoor heat exchanger 5 are connected in sequence by a refrigerant pipe. Each of diameters of heat transfer pipes 70 and 90 of a second outdoor heat exchanger 7 and an auxiliary indoor heat exchanger 9 located at a downstream side of a refrigerant flowing direction (each of arrows of broken line and solid line) in the case that the outdoor heat exchanger 3 and the indoor heat exchanger 5 become a condenser is smaller than a diameter of each of heat transfer pipes 60 and 80 of an upstream side first outdoor heat exchanger 6 and a major indoor heat exchanger 8.  Due to this fact, heat transfer of liquid refrigerant is promoted by an increased flow speed at the heat transfer pipes 70 and 90 of the second outdoor heat exchanger 7 and the auxiliary indoor heat exchanger 9 at the outlet port of the condenser. Accordingly, it is possible to increase a degree of supercooling of refrigerant at the outlet side of the condenser and increase a freezing capacity.
